1. INTRODUCTION

Hydro forming is a relatively new process, which uses water pressure to form complex shapes from sheet or tube material. Design studies suggest that automobiles can be made much lighter by using hydro formed components made of steel. Structural strength and stiffness can be improved and the tooling costs reduced because several components can be consolidated into one hydro formed part.
As the automobile industry strives to make car lighter, stronger and more fuel efficient, it will continue to drive hyd ....etc

VARI-FORM

ABSTRACT
The need for lighter, stronger, more rigid vehicle structures will increasingly require complex hydroformed structural tubes to increase strength, and decrease weight, cost and part count. This effort will increase the use of high strength, low alloy (HSLA) steel, in place of SAE 1006/1008 or 1010 steel. Traditional hydroforming techniques require the higher elongation of the latter materials. An alternative tube hydroforming process has been d ....etc

Sensorless Indirect Stator Field Orientation Speed Control for Single-Phase Induction Motor Drive
Abstract
The industrial requirements for the control of an inductionmachine without a mechanical sensor continue to be ofinterest, as evidenced by the most recent publications. The focusis on improvements of control without a mechanical sensor. A newmethod for the implementation of a sensorless indirect stator-fluxorientedcontrol (ISFOC) of a single-phase induction motor (SPIM)drive is proposed in this paper. The proposed method of rotor ....etc

Numerical simulation of rotor stator interaction is crucial for turbo machinery improvement since it allows the optimization of blade path design In addition the numerical simulation of rotor stator interaction makes it possible to predict the location and variation of hot spots on blades which is extremely useful in the turbine thermal design However simulation of rotor stator interaction is notorious for being computationally expensive To reduce the turnaround time and cost MFLOP a parallel code based on the message passing interface l ....etc

Double-Stator Switched Reluctance Machines (DSSRM): Fundamentals and Magnetic Force Analysis
Abstract
In this paper, a new switched reluctancemachine witha double-stator configuration (DSSRM) is introduced. The proposeddesign is based on optimization of themotional forces, whichleads to a high-grade electromechanical energy conversion process.A local examination of the force densities within and throughouta conventional switched reluctance machine (SRM) shows that themajority of the force produced is in the radial direction and doesno ....etc

INTRODUCTION
LARGE generators play a key role in power systems. Because they are expensive, unexpected breakdowns represent huge economic losses. High quality maintenance is therefore essential to ensure a high level of availability. In short, it is very important to ensure that large generators are in good repair and can run stably The vibration of stator bars caused by electromagnetic force exists in the operation of large generators and this is worsened by loose stator slot wedges. The severe vibration accel ....etc

Hydroforming (or hydramolding) is a cost-effective way of shaping malleable metals such as aluminum or brass into lightweight, structurally stiff and strong pieces. One of the largest applications of hydroforming is the automotive industry, which makes use of the complex shapes possible by hydroforming to produce stronger, lighter, and more rigid unibody structures for vehicles. This technique is particularly popular with the high-end sports car industry and is also frequently employed in the shaping of aluminium tubes for bicycle frames, Hydro ....etc
